A new vaccine against Ebola called VSV-ZEBOV demonstrated 100% efficacy ten days after being given to people who were not infected, according to findings published in the prestigious medical journal The Lancet . In the trial were involved 4,000 people who maintained close contact with the hemorrhagic virus in Guinea, one of the three countries affected by the current outbreak.
Because of the urgency required by this crisis, the clinical development of this vaccine is made from the initial human trial to demonstrate the efficacy and safety of the vaccine in a Phase III study in Guinea, in less than twelve months, a record time.
The vaccine trials were led by the World Health Organization (WHO), Medecins Sans Frontieres (MSF), the Norwegian Institute of Public Health and the Guinean authorities. They began in March this year in Guinea, and focus on the analysis of “circles” of people in the environment of infected patients, and front line workers at greatest risk of contracting the disease.
MSF is very involved in testing the vaccine and administered to 1,200 workers in Guinea, including doctors, nurses, paramedics, laboratory personnel and cleaning teams and funerals.
Dr Bertrand Draguez , who heads the MSF program on experimental techniques to combat Ebola, recognized that current data “tell us that the vaccine protects people against Ebola although the sample size is small and more research is needed. ” He said the magnitude of the public health emergency indicates that the vaccine used to protect workers will more risk or exposure.
“For the first time in history we have an effective vaccine against Ebola. This is an extraordinary development, but we need more research and analysis to find out how effective it really is a preventive tool: it is still unclear how the protection or how long it appears, “said Dr. Draguez, MSF
The on Friday, called ‘Blue Moon’, is a full moon as any. The plug ‘blue’ is only used to refer to that in the same month will be two full moons, so this star will be as usual, in gray, white or silver.
The phenomenon is explained by the fact that each lunar cycle lasts 28 days, so if Moon a month earlier, is probably a second at the end.
According to NASA, the last time there was a ‘Blue Moon’ was the August 31, 2012 and, after today, a similar astronomical event will be repeated 31 January 2018.
Although the term ‘blue’ finally speaks no color change in how we see this star, if there phenomena in which the Moon itself has seen that color, mainly after volcanic eruptions, such as occurred in 1883 after an earthquake Krakatoa volcano in Indonesia, whose ashes made the moon look like this.
Also, similar phenomena occurred in 1983 after the eruption of the El Chichon volcano in Mexico and in 1980 after the eruption of Mount St. Helens.
Similar phenomena have also been seen in areas devastated by forest fires, which causes changes in the tone of the reflection of the moon.
However, it is not the case of the phenomenon of Friday. The so-called ‘Blue Moon’ will, if weather conditions permit, as is usual and not as portrayed.
The founder of Facebook announced to his followers that he and his wife Priscilla are expecting a baby. Technological genius said he felt lucky and now it’s making a better world for her daughter.
Mark Zuckerberg is very happy to have a new member in your family. He revealed that a couple of years ago he and his wife have tried to have a child but had to overcome three miscarriages to reach this great moment. This phase of his life was hard, but conversarla with friends, managed to assimilate it.
If you have the freedom to communicate expecting a daughter is because pregnancy of Priscilla Chan progressing well and “is long enough” anymore. And they feel safer and the risk of loss is very low. They are hopeful.

Facebook announced two advances to provide Internet connectivity to more than 4,000 million people do not have access to the network, which has been its internet.org mission since they launched.
In this way, the connectivity equipment company run by Marck Zuckerberg presented its drone named Aquila, solar powered energy and capable of flying for 90 days at a height from 18.000 to 27,000 kilometers.
In turn, has a carbon fiber frame and unique design, this unmanned aerial vehicle can not reach remote areas to provide connection.
The company also introduced a laser that can deliver data 10 times faster than currently possible and only aiming at a target the size of a penny provides Internet 10 kilometers away.
Today, the firm continues with the evidence of the laser in real conditions and when the system is completed, can be used to connect the aircraft with one another and with the ground.
This, he said, would create a stratospheric network that can extend to the farthest regions.
The success of a vaccine against Ebola paves the way to end and stop deadly virus outbreak in Africa.
(Reuters) .- The first world is poised to protect humans from Ebola, he reported the World Health Organization ( WHO ) after the results of a trial in Guinea showed that a vaccine is 100% effective.
Initial results of a study that evaluated the immunization of Merck and NewLink Genetics called VSV – ZEBOV in more than 4,000 people who had been in direct contact with a patient with a confirmed diagnosis of Ebola, they showed 100% protection after ten days.
The data were described as “exceptional” and “revolutionary” by specialists in global health.
“We believe the world is about to have an effective vaccine Ebola” said the expert on immunizations WHO Marie Paule Kieny, at a press conference in Geneva.
The vaccine can now be used to help end the worst outbreak of Ebola on record, killing more 11,200 people in West Africa since its inception in December 2013.
The general director of the WHO , Margaret Chan, said the results of study, published in the online edition of the medical journal The Lancet, were “extremely promising development”
“This is going to be revolutionary,” Chan told reporters. “It will change the handling of the current outbreak of Ebola and future outbreaks,” said
This and other trials of experimental immunizations were accelerated with a huge international effort., As investigators struggle to achieve test potential therapies and vaccines in a time when the virus is in full flow.
“We knew it was a race against time and the trial had to be implemented under the most challenging circumstances,” he says John-Arne Röttingen, chief of infectious disease control at the Norwegian Institute of Public Health and president of the group that led the trial.
ring vaccination trial Guinea to assess the effectiveness and safety of the vaccine began on March 23. A single dose of VSV was tested – ZEBOV using the strategy of “ring vaccination” in which people close to someone diagnosed with Ebola were immunized either immediately or a few days later.
As began to emerge data showing a high rate of protection among vaccinated immediately, researchers on July 26 decided not to use more strategy “delayed” since beginning to be clear that waiting involved unethical and unnecessary risk.
The trial continues and all participants receive a dose of the vaccine immediately. It will he extended to include children of 13-17 years and possibly to less than 6-12, said the WHO .
“Our hope is that the vaccine now will help us to stop this epidemic (in Africa) and prepare for the inevitable future epidemics of Ebola, “said Jeremy Farrar, infectious disease specialist and director of the Wellcome Trust charity.
Doctors Without Borders, which has led the fight against Ebola in West Africa, is calling for VSV – ZEBOV is applied in other epicenters of the current outbreak, Liberia and Sierra Leone, where they believe it may cut the chains of transmission and protect health workers.
experimental vaccine proven in thousands of people exposed to Ebola in Guinea it seems to be working and may assist in the eradication of epidemic currently afflicting West Africa, according to results of a study published on Friday.
There are currently no approved treatment or vaccine for Ebola, which has so far killed more than 11 000 people since last year began the world’s largest outbreak.
If it proves to be effective, the vaccine could “alter the landscape,” said Dr. Margaret Chan, Director General of the World Health Organization, which sponsored the study.
In a 4000 people who had contact with Ebola and received the vaccine 10 days, there have been no contagion. That compares with 16 positive cases in 3000 more than 500 people who received immunization 10 days after contact.
A vaccine against Ebola virus was effective at 100 percent for a clinical trial on the ground, in Guinea, more than 4,000 people, announced on Friday the main participants in the project.
“An effective vaccine against the Ebola virus is to reach globally,” he said in a statement the World Health Organization (WHO) He spoke of a “very promising development.”
The first results, published in the British medical journal The Lancet, show that VSV-ZEBOV vaccine demonstrated a efficiency of 100 percent in the first 10 days after administration in an uninfected person, but in contact with the sick.
The vaccine was developed by the Public Health Agency of Canada (PHAC) and the license was submitted by the US Merck and NewLink Genetics Corp. The trial was made possible by a major international cooperation involving the WHO and experts from Norway, France, Switzerland, United States, United Kingdom and Guinea.
“If the results are confirmed, this new vaccine could be the miracle cure for Ebola and help halt the current epidemic and curb similar epidemics in the future,” he said by Meanwhile Borge Brende, Norwegian Minister of Foreign Affairs.
The current Ebola epidemic, which broke out in Guinea in December 2013 and is the most serious in West Africa since it was identified this virus in central Africa in 1976, left 11,279 dead among 27 748 cases, a balance that the WHO considers even underestimated.
VSV-ZEBOV The vaccine is one of the two most advanced vaccines against the virus. The other, developed by the British firm GSK (GlaxoSmithKline) and the American Institute of Allergy and Infectious Diseases (NIAID), is currently being tested in Liberia.
Chihuahua – tonight to pass the so-called “Blue Moon” astronomical event; it is a second full moon in the same month. That although the name that calls this succession of 2 moons, has nothing to do with the color of the natural satellite, definitely worth watching the moon tonight, since this phenomenon happens every three years.
Eduardo Balderrama Peña, member of the Astronomical League of Chihuahua, told how this astronomical phenomenon is due.
“The fact that it is possible to have two full moons in the same month is due to the cycle of the full moon is approximately every 29.5 days, so if the full moon occurs on the first or second day of the month, there is likelihood that a second full moon in recent days appears, what we would call a Moon blue. This phenomenon occurs every three years “
In this month came a full moon day 2, so this is a succession. However, since it began releasing the astronomical event most people wonder if the satellite actually shine in blue tone today.
clarified that “the term blue moon, not means the moon will look splendid blue as much misinformation quotes.
Finally advised that those who leave tonight to see at a glance the satellite, do not do with binoculars or telescope, “.. .pues the lunar disk to be complete emits a lot of light and using an instrument of optical magnification, it can hurt the hearing by the dazzle of light in the eye “.
Worth going out tonight to enjoy a second full moon in the same month as those who lost the show moon will have to wait until January 2018 when it will be repeated the astronomical phenomenon.

If you’ve lost and you do not get to send a WhatsApp to your friends and you also manage to call them, you have the option to communicate “off-net”. We explain four ways to do so.
Show your Latin pride! Follow the voice of the Hispanics on Facebook!

You came in groups to the concert but suddenly you find yourself alone in a crowd.
And you are such a fan of the band wanted to be as close to the stage. But when you look back, do not find a single familiar face.
So you try to WhatsApp. “Where are they?”, Type in the free messaging application, but do not manage to send the text.
And when you try to call, either you get tone. The networks are overloaded.
What, then, to communicate with your friends?
Do not despair, these four options you will draw trouble .
You can try to send a message conventional text SMS.
And, even without internet connection, can we do have network GMS , global system for mobile communications (English Global System for Mobile communications).
The SMS do not usually have a high price and although not the best choice for a long conversation, are useful for contact with someone of urgency.
The best known are the application of Android and Hangouts messages, but there are many other options on Google Play, as Textra.
In this line, the company Navenetworks EnviaSMS developed the service.
With this the recipient will receive the message being disconnected from the Internet. The only requirement is that both sender and receiver have the application installed on your smartphone and EnviaSMS the issuer itself that is connected to the internet via wifi or data.
It was already used during protests in Iran and in Taiwan, but this application of the US company Open Garden became known in the pro-democracy demonstrations last year in Hong Kong .
In September, in just 24 hours 100,000 people the app is downloaded in the special administrative region of China.
And that is found in it a way to communicate when Instagram had been blocked in China and many more messages than usual were censored at the Chinese site microblogging Sina Weibo, similar to Twitter.
Firechat allowed them to communicate with each other even without access to phone or internet coverage.
The application powered by other mobile yes they are connected to the wireless network and act as an access point to the terminal that is not .
After installing in them the application, these are interconnected through WiFi antenna lead built in, which allows messages ever-expanding chain, jumping from one user to another nearby.
This application uses the same technology as Firechat, and hence comes the name . mesh networking or wireless mesh network
And like Firechat serves not only to communicate through demonstrations or when there is censorship in social networks
it is also useful in festivals or other events where typical networks are overloaded, as well as in the mountains or other places with little or no coverage.
You MeshMe offers communicate with other users when your smartphone is in airplane mode, provided you keep the WIFI and Bluetooth Connected .
Each cell that has the application installed will function as a router , and pass the information to another device using the most efficient way at the time.
But the owners of the phones are being used as a node can not read the text unless it is addressed to them.
According to company, an iPhone 6 MeshMe should be able to transfer data at a distance between 20 and 30 meters using wireless sign, and 10 and 15 meters using Bluetooth.
This option is not an application that you can download on your phone, but mobile accessory that serves as anten .
It is a product of a start-up New York of the same name, a pocket-sized bar with a strap to attach it to a backpack or belt hanging.
Since the Apps above, goTenna allows communication point by point, but as long as users of the devices to have the accessory.
What it does is create a network of low-frequency radio for IOS and Android .
No can expect a communication with an extraordinary band width, but the CEO of the company, Daniela Perdomo, said that open horizons can send up to 80 meters distance .
All communications are encrypted has a constant forwarding system , to make sure the message has reached its recipient.
Whether you opt for this fixture as any of the above apps, it will be a more effective way to meet your friends to wait at the door of the concert until the place is empty.
The social network Facebook announced built a giant drone can fly at a height of up to 27.5 kilometers and which seeks to bring internet to remote areas of the planet.
The UAV, which Facebook has given the name of Aquila and is powered by solar energy , you can stay in the air for a period of 90 days .
The project is part of the Internet.org initiative with Facebook wants to facilitate access to the web in developing countries.
“Since launched internet.org our mission has been to find ways to facilitate connectivity more than 4,000 million people that are not yet online, “the company said in a statement.
Facebook stated that partnerships with mobile operators in 17 countries for the last year have facilitated access to internet service basic more than 1,000 million people .
To achieve its goal of bringing Internet to the corner of the world, Facebook is in addition to working on drones, in satellites, lasers and terrestrial technology. (EFE)
trees need an average of two to four years to recover their growth rates after severe droughts, a longer period of established by global models that relate climate and vegetation, and assume an almost immediate recovery.
The study, published in the Science , suggests, therefore, that the forests, as a result of the slow recovery after a drought, are can store less carbon than previously estimated with models of climate and vegetation and this would imply that the Climate Change can also be faster than previously thought.
These are among the findings of a team led by William RL article Anderegg, University of Utah (USA), and the Spanish side signing Julio Camarero Jesus, scientist of the Higher Council for Scientific Research (CSIC) in the Pyrenean Institute of Ecology (Zaragoza).
The forests play an important role in the damping of climate change caused by human activity: trees set much of the CO2 through photosynthesis and convert and store some of that synthesized carbon as wood.
This regulation of the global carbon cycle is critical for the planet, stressed Efe Waiter, and the finding that drought stress slows tree growth over the years indicates that forests are able to store less carbon than calculated.
“If forests are not as good retaining carbon dioxide, this means that climate change could accelerate,” Anderegg said in a press release from the University of Utah.
WASHINGTON, EU., July 30. 2015.- The Philae module which made history last November to successfully land on the comet 67P, found organic compounds considered precursors of life, reported the American Association for the Advancement of Science (AAAS).
The association today published a series of articles with scientific discoveries made with data Philae has been sending Rosetta from the European Space Agency which broke away to land on 12 November in comet 67P ( 67P / Churyumov-Gerasimenko).
In a study that appears published in the journal Science, the researchers explain that the Cometary Sampling and Composition (COSAC), one of the main instruments of Philae module, determined the existence of organic material in the comet.
Just 25 minutes after landing on the comet, the mass spectrometer of the COSAC took a measurement mode “sniffing”, similar to chemical detectors airports, which revealed the presence of 16 organic compounds, some with none nitrogen and sulfur, according to the study.
Many of these components were detected in the tail of most comets, but methyl isocyanate, acetone, propanal and acetamide compounds that had not been discovered earlier in other comets was also found.
But most important for astrobiology is that some of the materials found in comet dust are considered precursors of life, as involved in the formation of essential amino acids or nucleic bases.
The researchers stressed that comets preserve the pristine material in our solar system in the form of ice, dust, silicates and solid organic matter, which probably formed in interstellar space even before the solar nebula which then became the solar system appear.
The study of the chemical composition of comets also provides crucial information on this in the early solar system matter, whose study is of great importance from the geological point of view because it provides some of the keys to understanding how his training.
In addition, from the point of view of habitability, can help us understand the origin of water on Earth and other planets like Mars and, from the point of view astrobiology, are fundamental to understanding the origin of life on this planet.
Other studies released today describes the time when the robot Philae held its rugged arrival at the surface of the comet 67P, with three landings and two rebounds.
After rebounding in the designated landing area, that turned out to have a layer of about 25 soft and grainy centimeters, the module finally stopped in a remote area of rocky consistency, the edge of a crater and on uneven terrain.
The analysis of the two surfaces different consistencies and provided data on the evolution of comets and could serve to improve the design of new missions to others.
The analysis conducted by scientists from the data sent by Philae through Rosetta probe suggest that the landscape of Comet 67P has formed through erosion.
To get a clearer picture of the interior of the comet, scientists counted on measurements obtained from Philae directing electromagnetic signals through comet nucleus to be received by Rosetta on the opposite side.
These measurements suggest that the head of the comet has a fairly homogeneous composition and its interior is even.
To receive information Philae, the Rosetta probe has flown so far in optimal orbit to establish that communication, but on July 24 went to move over the southern hemisphere of the comet’s sunlit, to switch communication with the observation of Philae 67P / Churyumov-Gerasimenko.
ejections of gas and dust in the comet’s surface prevent Rosetta fly very close to the surface and force the probe is kept at a safe distance of between 170 and 190 km.
Google refuses to obey an order of French authority to cancel search results around the world, when people claim their “right to be forgotten” online, the company said, exposing themselves to potential fines.
The authority of French data protection, the CNIL, in June ordered the company to hide search engine search requests that deliver results displayed under the name of a person in all websites, including Google.com
This is derived from a regulation by the European Court of Justice in May last year. European residents claim that in search engines such as Google or Microsoft Bing should proceed eliminating results that appear under the search for a name when they are not recent, are irrelevant and even are incendiary. This is the famous right to be forgotten.
Google due to regulation and, since then, has received more than a quarter of a million requests for removal of results, in accordance with its reporting transparency. The company has cooperated with 41 percent of requests.
However, it has limitations as to the removal of European sites such as Google.fr Google.de in Germany or in France, arguing that more than 95 percent of European searches are conducted through local versions of Google.
